BACKGROUND Technical Field

The present invention relates to compound for organic electronic element, organic electronic element using the same, and an electronic device thereof.

Background Art

In general, organic light emitting phenomenon refers to a phenomenon that converts electronic energy into light energy by using an organic material. An organic electronic element using an organic light emitting phenomenon usually has a structure including an anode, a cathode, and an organic material layer interposed therebetween. Here, in order to increase the efficiency and stability of the organic electronic element, the organic material layer is often composed of a multi-layered structure composed of different materials, and for example, may include a hole injection layer, a hole transport layer, an emitting layer, an electron transport layer, an electron injection layer and the like.

A material used as an organic material layer in an organic electronic element may be classified into a light emitting material and a charge transport material, such as a hole injection material, a hole transport material, an electron transport material, an electron injection material and the like depending on its function.

In the case of a polycyclic compound containing a heteroatom, the difference in properties according to the material structure is so large that it is applied to various layers as a material of an organic electronic element. In particular, it has characteristics of different band gaps (HOMO, LUMO), electronical characteristics, chemical properties, and physical properties depending on the number of rings, fused positions and the type and arrangement of heteroatoms, therefore application development for layers of various organic electronic elements using the same has been progressed.

As a representative example thereof, in the following Patent Documents 1 to 4, the performance of the 5-membered cyclic compound in the polycyclic compound has been reported depending on the hetero type, arrangement, substituent type, fused position, and the like.

[Patent Document 1]: U.S. Pat. No. 5,843,607

[Patent Document 2]: Japanese Laid-Open Patent Publication No. 1999-162650 [Patent Document 3]: Korean Published Patent Application No. 2008-0085000 [Patent Document 4]: US Patent Publication No. 2010-0187977 [Patent Document 5]: Korean Published Patent Application No. 2011-0018340 [Patent Document 6]: Korean Published Patent Application No. 2009-0057711

Patent Documents 1 and 2 disclose an embodiment in which the indolecarbazole core in which the hetero atom in the 5-membered cyclic compound is composed only of nitrogen (N) is used, and an aryl group substituted or unsubstituted in N of indolocarbazole is used. However, in the prior invention 1, there exists only a simple aryl group substituted or unsubstituted with an alkyl group, an amino group, an alkoxy group, or the like as a substituent, so that the effect of the substituents of the polycyclic compounds was very poor to prove, and only the use as a hole transport material is described, and the use thereof as a phosphorescent host material is not described.

Patent Documents 3 and 4 disclose a compound in which pyridine, pyrimidine, triazine or the like containing an aryl group and N, respectively, were substituted for an indolecarbazole core having a hetero atom N in the same 5-membered cyclic compound as in the above Patent Documents 1 and 2, however only the use examples for phosphorescent green host materials are described, and the performance for other heterocyclic compounds substituted for indolecarbazole core is not described.

In Patent Documents 5, Nitrogen (N), oxygen (O), sulfur (S), carbon and the like are described as heteroatom in the 5-membered cyclic compound, however there are only examples using the same heteroatom in the performance measurement data, the performance characteristics of a 5-membered cyclic compound containing a different heteroatom could not be confirmed.

Therefore, the patent document does not disclose solutions to low charge carrier mobility and low oxidation stability of a 5-membered cyclic compound containing same heteroatom.

When the 5-membered cyclic compound molecules are generally laminated, as the adjacent π-electrons increase, they have a strong electronical interaction, and this is closely related to the charge carrier mobility, particularly, the same 5-membered cyclic compound of N—N type has an edge-to-face morphology as an order of arrangement of molecules when molecules are laminated, otherwise a different 5-membered cyclic compound with different heteroatoms has an antiparallel cofacial r-stacking structure in which the packing structure of the molecules is opposite to each other, so that the arrangement order of the molecules becomes face-to-face morphology. It is reported that the steric effect of the substituent substituted on the asymmetrically arranged hetero atom N as the cause of this laminated structure causes relatively high carrier mobility and high oxidation stability (Org. Lett. 2008, 10, 1199).

In Patent Document 6, an example of using as a fluorescent host material for various polycyclic compounds having 7 or more membered cyclic compounds has been reported.

As described above, the fused positions, the number of rings, the arrangement of heteroatoms, and characteristic change by type of the polycyclic compounds have not yet been sufficiently developed.

Particularly, in a phosphorescent organic electronic element using a phosphorescent dopant material, the LUMO and HOMO levels of the host material have a great influence on the efficiency and life span of the organic electronic element, this is because the charge balance control in the emitting layer, the quenching of the dopant, and the reduction in efficiency and life span due to light emission at the interface of the hole transport layer can be prevented, depending on whether electron and hole injection in the emitting layer can be efficiently controlled.

For fluorescent and phosphorescent host materials, recently we have been studying the increase of efficiency and life span of organic electronic elements using TADF (thermal activated delayed fluorescent), exciplex, etc., particularly, and many studies have been carried out to identify the energy transfer method from the host material to the dopant material.

Although there are various methods for identifying the energy transfer in the emitting layer for TADF (thermally activated delayed fluorescent) and exciplex, it can be easily confirmed by the PL lifetime (TRTP) measurement method.

The TRTP (Time Resolved Transient PL) measurement method is a method of observing a decay time over time after irradiating the host thin film with a pulsed light source, and therefore it is possible to identify the energy transfer method by observing the energy transfer and the lag time. The TRTP measurement can distinguish between fluorescence and phosphorescence, an energy transfer method in a mixed host material, an exciplex energy transfer method, and a TADF energy transfer method.

There are various factors affecting the efficiency and life span depending on the manner in which the energy is transferred from the host material to the dopant material, and the energy transfer method differs depending on the material, so that the development of stable and efficient host material for organic electronic element has not yet been sufficiently developed. Therefore, development of new materials is continuously required, and especially development of a host material for an emitting layer is urgently required.

As can be seen from the results of Table 7 and 8, when the organic electric element material of the present invention represented by Formulas (1) and (2) is mixed and used as a phosphorescent host (Examples 1 to 61), it was confirmed that the driving voltage, efficiency, and life span were significantly improved as compared with the element using a single material (comparative examples 1 to 7).

More specifically, in Comparative Examples 1 to 7, wherein the compounds of the present invention represented by Formula (2) and comparative compounds 1 to 4 are used alone as a phosphorescent host, Comparative Examples 1 to 3 using the compounds (3-6, 3-61, and 3-74) of the present invention had higher efficiency and longer life span than Comparative Examples 4 to 7 using the comparative compound.

Also, Comparative Example 8 and 9 wherein Comparative Compound 1 and 2 or Comparative Compound 3 and 4 were mixed and used as a phosphorescent host were found to exhibit higher efficiency than Comparative Examples 1 to 7 using the single substance.

Comparing Comparative Example 8 with 9, Comparative Example 9 using a mixture containing a polycyclic compound having a different heteroatom (N, S) among the 5-membered compounds had higher efficiency than Comparative Example 8 mixed a 5-membered heterocyclic compound having the same nitrogen atom.

And it was confirmed that Example 1 to 61 using the mixture of the compound of Formula (1) and (2) as a host exhibited remarkably high efficiency and long life span than the Comparative Example 1 to 9.

On the basis of the above experimental results, the inventors of the present invention have found that, in the case of a mixture of the substance of Formulas (1) and (2), they have novel characteristics other than those for the respective materials, and have measured the PL lifetime using the substance of Formula (1), the substance of Formula (2), and the mixture of the present invention. As a result, it was confirmed that a new PL wavelength was formed when the compounds of Formulas (1) and (2) were mixed, and the decreasing and disappearing time of the newly formed PL wavelength increased from about 60 times to about 360 times compared to the reduction and disappearance times of substances Formula (1) and (2), respectively. It is considered when mixed with the compound of the present invention, not only electrons and holes are moved through the energy level of each substance, but also the efficiency and life span are increased by electron, hole transport or energy transfer by a new region(exciplex) having a new energy level formed due to mixing. As a result, when the mixture of the present invention is used, the mixed thin film is an important example showing exciplex energy transfer and light emitting process.

The reason why the combination of the present invention is superior to Comparative Examples 8 to 9 in which a comparative compound is used as a phosphorescent host is that the high Ti and high LUMO energy values improve the electron blocking ability and allow more holes to be moved to the emitting layer more quickly and easily when a compound represented by Formula (1) having a strong hole property is mixed with a polycyclic compound represented by Formula (2), which is characterized not only by electron but also by hole stability and high Ti. As a result, the charge balance in the emitting layer of holes and electrons is increased, so that light emission is well performed inside the emitting layer rather than at the interface of the hole transport layer, and therefore the deterioration in the HTL interface is also reduced, thereby maximizing the driving voltage, efficiency and life span of the device.

Among the compounds represented by Formula (1), 1) when Ar¹ and Ar² are of the type in which the ring is curled, it has been confirmed that compounds having at least one of Ar³ and Ar⁴ substituted with biphenyl exhibits the best results in terms of the driving voltage, the efficiency and the lifetime, and compounds having at least one of Ar³ and Ar⁴ substituted with Dibenzothiophen or Dibenzofuran were found to be excellent in efficiency and lifetime, and in the case of compounds in which at least one of Ar³ and Ar⁴ is substituted with fluorene, the driving voltage is excellent. 2) When Ar¹ and Ar² do not form a ring, compounds in which both Ar³ and Ar⁴ were substituted with naphthyl showed the best results in terms of driving voltage, efficiency, and lifetime, and compounds having at least one of Ar³ and Ar⁴ substituted with Dibenzothiophen or Dibenzofuran were confirmed to have excellent efficiency and lifetime. That is, it is concluded that the combination of Formula (1) and Formula (2) is electrochemically synergistic to improve the performance of the device as a whole.

Also, Table 8 shows the results obtained using Table 7, in which a first host with high performance was fixed and a variety of second hosts were mixed. As a result, as the first host, when compounds 1-3, 1-10, 2-1 and 2-14 having the best driving voltage, efficiency, and lifetime and, as the second host, the compounds 3-7, 3-8, 3-9, 3-15, 3-37, 3-46, 3-50, 3-61, 3-74, 3-89 and 3-90 were mixed, it can be seen that the driving voltage, efficiency and lifetime can be remarkably improved by using two mixed host materials as compared with the case of using a single host material.

An organic electroluminescent device was manufactured in the same manner as in Example 1, except that the materials are used in different mixing ratios as listed in Table 9.

As shown in Table 9, the mixture of the compound of the present invention was measured by fabricating the device in (2:8, 3:7, 4:6, 5:5). To explain the results in detail, in the result of the mixture of the compound 1-3 and 3-6, the results of the driving voltage, the efficiency and the life span were similarly excellent at 2:8 and 3:7, but as the ratio of the first host increases, such as 4:6 and 5:5, the results of the driving voltage, the efficiency and the life span are gradually decreased, this was also the same in the result of the mixture of the compound 2-1 and 3-61. This can be explained by the fact that the charge balance in the emitting layer is maximized when an appropriate amount of the compound represented by Formula (1) having strong hole properties such as 2:8 and 3:7 is mixed.

As can be seen from the results of Table 10, when the compound of the present invention represented by Formula (1) is used as a material for the emitting auxiliary layer and the compound of the present invention represented by Formula (2) is used as a phosphorescent host material (Examples 70 to 85), the driving voltage, the efficiency, and the lifetime were significantly improved as compared with the device using a single material (Comparative Examples 10 to 14).

In detail, in Comparative Examples 10 to 14 using the compound of the present invention represented by the formula (2) or Comparative Compound 5 alone as a phosphorescent host, Comparative Examples 11 to 14 using the compounds of the present invention (3-6, 3-7, 3-8, and 3-101) exhibited higher efficiency and longer lifetime than Comparative Example 1 using Comparative Compound 5.

It was also confirmed that Examples 70 to 85 using the compounds of Formula (1) and Formula (2) of the present invention, as the emitting auxiliary layer and the phosphorescent host, respectively, show significantly higher efficiency, lifetime and low driving voltage than the Comparative Examples 10 to 14.

In general, there is an injection barrier between HTL and EML, so that the hole can not be transferred easily, and the charge balance is not matched so that the driving voltage is increased. Therefore, it is considered that the charge balance in the emitting layer of the hole and electron is adjusted by the introduction of the emitting auxiliary layer having a proper HOMO level between HTL and EML when the emitting auxiliary layer of the present invention is applied.

Specially, a compound in which at least one of Ar¹, Ar², Ar³, Ar⁴, L¹, L², L³, L⁴, and L⁵ is substituted with a dibenzothiophene or dibenzofuran exhibited remarkably higher refractive index and higher Tg as compared with the case where the substituent of the general aryl group was substituted, so that the efficiency and the thermal stability were improved, and it was judged that the compound showed improved device results.

The compound of the present invention represented by Formula (1) suitably align the barriers of HTL and EML so that the device has a feature of high hole mobility, and compounds of the present invention represented by Formula (2) have characteristics of not only fast electron mobility but also hole stability and high Ti as compared with Comparative compound 6. Therefore, the combination of the two makes it possible to move more holes to the emissive layer quickly and easily. As a result, the charge balance in the emitting layer of holes and electrons is increased, so that light emission is well performed inside the emitting layer rather than at the interface of the hole transport layer, and therefore the deterioration in the ITO and HTL interface is also reduced, thereby maximizing the driving voltage, efficiency and life span of the device. That is, it is judged that the combination of the compound of the present invention represented by Formula (1) and the compound of the present invention represented by Formula (2) is electrochemically synergistic to improve the performance of the device as a whole.
